UNITED STATES PATENT oEErcEi GEORGE N. SAEGMULLER, OF ROCHESTER, NEW YORK.

SURVEYING INSTRUMENT.

T 0 all whom it may concern:

Be it known that I, GEORGE N. SAEG- MULLER, a citizen of the United States, re-

siding at Roch-ester, in the county of Mon roe and State of New York, have invented certain new and useful Improvements in Surveying Instruments, of which the following is a specification.

This invention relates more particularly to the supporting frame for the telescope.

The principal object is to provide a novel and simple article of manufacture in which the compass box and the telescope supporting standards are cast in a single piece and said standards have great strength and resistance against lateral strains and vibratlons.

A further object is to construct the suporting frame so that the necessary plate or ass for the adjusting screws can be more easily and efliciently secured in position.

The preferred form of construction is illustrated in the accompanying drawings, where- 111:

Figure 1 is a perspective view of the frame. Fig. 2 is a vertical sectional view therethrough. Figs. 3 and 4 are respectively horizontal sectional views on the lines 33 and 44l of Fig. 2. Fig. 5 is a vertical sectional view on the line 5-5 of Fig. 4.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment disclosed, a compass box is employed, comprising a substantially circular ring 6 provided with an internal shoulder 7 constituting a support for the compass scale ring 8. Rising from the opposite sides of the compass ring and integral therewith, are telescope supporting standards 9. Each of these standards consists of convergently disposed side bars 10, each side bar comprising angularly disposed flanges 11. The said side bars have their lower portions outwardly curved, as shown and integrally joined to the outer sides of the compass box 6, thus producing in effect outstanding lugs 12 on said compass box. The central portions of the side bars of each standard are joined by suitable webs 13, and their upper ends are connected by integral head pieces 14 having suitable seats 15 for the reception of the telescope journals or mountings. The plate or disk against which the adjusting screws bear, is shown at 16, and is located against the under side of the compass box,

as illustrated. It is secured in place by suitable screws 17 or other fasteners, which, as illustrated in Figs. 4 and 5, are passed upwardly through said disk or plate into the under side of the com ass box at the thickened portions formed by the lugs 12 or lower ends of the standards. These screws terminate short of the upper face of said compass box. W'ithin the compass box is a post 18, upon which is journaled the compass needle 19, the ends of which cooperate with the scale upon the ring 8.

T he structure can be mounted in the customary or any suitable manner so that it will rotate about a vertical axis, and it may therefore be provided with a depending plug, as 20, shown in Fig. 5. The telescope journal blocks can also be fastened in the seats 15 by any desirable means, as for instance, screws 21.

It will be evident that this structure is exceedingly simple, and yet is very strong, the standards being so arranged that they will resist all lateral strain or pressure. The compass box furthermore constitutes a base and integral connection between the standards, and furthermore the structure permits the lower plate or disk 16 to be rigidly secured in position.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention, will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As an article of manufacture, a telescope frame comprising a compass box comprising side walls, and telescope supporting standards integral with and joined to the outer sides of the compass box.

2. As an article of manufacture, a telescope frame comprising a compass box having substantially circular side walls, and upwardly and outwardly curved telescope supporting standards integral with and joined to the outer sides of the compass box.

3. As an article of manufacture, a telescope frame comprising a compass box ring, and oppositely disposed telescope supporting standards integral with and joined to the outer sides of the ring, said standards each comprising spaced connected side bars formed of angularly disposed flanges, said bars having their lower portions outwardly curved and their upper portions substantially vertical, said upper portions being provided with seats for the reception of telescope journals.

4. As an article of manufacture, a telescope supporting frame comprising a compass box, standards rising from the outer sides of the box forming outstanding lugs on said box, a base plate located against the under side of the box, and fasteners passing through the base plate into the under side of the box at said lugs.

5. As an article of manufacture, a telescope supporting frame comprising a compass box ring, and oppositely disposed telescope supporting standards, said standards. each comprising spaced connected side bars formed of angularly disposed flanges, said bars having their lower portions outwardly curved and integrally joined to the outer sides of the compass ring, forming sets of oppositely outstanding lugs on said rings, the up er portion of said bars being substantia ly vertical, and connections between the upper ends of the bars, said connections being provided with seats for the reception of telescope journals.

In testimony whereof I affix my signature, in presence of two witnesses.
